Diaphysis-
the bone's shaft/body
long, cylindrical main portion of the bone
Epiphysis-
distal and proximal ends of the bone
2 per long bone
Metaphysis-
where the epiphysis meets diaphysis
Epiphyseal plate-
a layer of hyaline cartilage located in the metaphysis of growing long bones
allows bone to grow in length
Epiphyseal Plate-
After the bone stops growing the cartilage is replaced by bone
Articular Cartilage-
a layer of hyaline cartilage that covers the part of the epiphysis where the bone articulates
serves to reduce friction, absorb shock at movable joints
Periosteum-
tough sheath or dense irregular connective tissue surrounding bone forming cells
contains bone forming cells
allows bones to get thicker, not longer
assists in repair
nourishes bone
serves as attachment for ligaments and tendons
medullary cavity-
marrow cavity
space in shaft
contains fatty yellow marrow in adults, red marrow in children
